KTM’s 250 SX-F is stronger than ever in terms of peak horsepower and torque figures when run on our in-house Dynojet 250i rear-wheel dynamometer.<br /><br />--<br /><br />After giving us a preview with its 250 SX-F Factory Edition and 450 SX-F Factory Edition near the end of MY22, KTM unveiled its next-generation motocross and cross-country models last year. Shared updates among the SX, SX-F, XC, and XC-F models included a new frame, subframe, swingarm, shock, and bodywork. Engine updates were specific to each displacement of two-stroke and four-stroke.<br /><br />For the 250 SX-F, this meant a fully redesigned DOHC cylinder head, 3mm larger bore, 3.8mm shorter stroke, and slightly increased compression ratio. The prior-generation (2019–2022) model was already a top performer on the Dirt Rider dyno. Could KTM improve on that even further?<br /><br />Yes. The 2023 model spun 41.5 hp and 19.5 lb.-ft. of torque—an increase of 1.7 hp and 0.4 lb.-ft. of torque at peak. In addition to making the most peak torque in the class, the 250 SX-F sits runner-up in maximum horsepower just behind its Austrian cousin, the Husqvarna FC 250. The orange machine’s fuel-injected liquid-cooled DOHC four-stroke 250cc engine was one of the reasons it fared so well in our 2023 250F Motocross Shootout.<br /><br />“I really like the power delivery of the KTM, especially in the aggressive map 2 (green light illuminated) as it improves low-end,” test rider Michael Wicker said. “Like previous years, this engine suits riders who stay high in the rpm range, so I don’t recommend relying too heavily on its bottom-end. Nonetheless, the 250 SX-F is no slouch on overall power.”<br /><br />Full story here: https://www.dirtrider.com/tests/ktm-250-sx-f-dyno-test-2023/<br /><br />Video By: Bert Beltran<br /><br />Read more from Dirt Rider: https://www.dirtrider.com/
